Certainly, not having all their eggs in one basket is working in QCOM's favor.
Huh? You were talking about QCOM's supposed advantages of being a fabless company, which you said allowed them to have higher profit margins.
But being fabless isn't the reason that they are. The fact that they were once an IP-only company that made their revenues almost exclusively by licensing is the reason.
Now they're actually producing components of their own (though foundries, of course). The margins here are not any better than those of Intel.
